MECHANISM FOR OPERATlNG VALVES F TANKS FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent N 0. 757,738, dated April 19, 1904.

Application filed March 26, 1 903. Renewed February 27, 1904. Serial No, 195,549. (Ndmodeld To all whom it may concern:

. Be it known thatLPETER J. GRoss,a resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Mechanisms for Operating Valves of Tanks for Water-Closets, of which the following is a full, clear, and exact specification, reference being had to the ac open and the mechanism for operating them in position immediately preceding to that of closing the outlet-valve. Fig. 3isap1an view of the tank and mechanism, showing the'parts in the same position as shown in Fig. 1. Fig. 4 is a view similar to Fig. 1, but showing the mechanism operating the valves in the position when automatically opening the outletvalve to preventan overflow of the tank. Fig. 5 is an enlarged detail view of a part of the mechanism as it appears in sectional view on line 5 5 indicated in Fig. 1. Fig. 6 isasimilar view like Fig.5, but showing the partin position when holding the lever operating the discharge-valve in lifted position. Fig. 7 is a similar enlarged detail partly-sectional view like Fig. 5, but showing the position of parts appearing on line 77 indicated in Fig. .2.

My invention relates to sanitary-plumbing appliances;and it consists of the hereinafter de-.

' scribed mechanism for so operating the valves of a water-tank to prevent an excessive discharge and overflow of thewater and, which is yet more important, to prevent ingress of air in the conduits, and thereby the rumbling and hissing noise attending the discharge of water from the tank and the refilling of the tank after the overflow is stopped.

-Referring to the drawings, and more particularly to Fig. 1, A is a water-tank of the type and size usually employed. a is a lug supported on bracket Z wherein lever 0 is i the outlet-tube V the lever c.

I fulcrnmed on pin OZ. 4 To the outwardly-proprovided with a valve of the ordinary kind,

operated by lever Z and floating ball Z, secured to the end thereof in the usual mannerto wit, when the level of the water in the tank sinks and the ball is drawn downwardly the inlet-valve, is opened by the downward swing of lever Z, and when the level of the water rises, lifting float Z to a certain predetermined height, the inlet-valve is closed. In addition to this mechanism which is ordinarily employed in such tanks I provide the following mechanism for the accomplishing of the stated purpose: Across the tank A is set platform m, whereon lug n is secured, whose prongs n and n serve as guides for Adjoining these prongs hooks 0 are provided, and on these hooks is fulcrumed thelever 10. On the opposite side of the plat form lug g is aflixed to it or made integral therewith. To this lug a drop-trigger q is pivoted, turning freely on pin q, screwed or otherwise secured in the lug. The drop-trigger Q is shownin Figs. 5, 6, and? on enlarged scale. Its head is cam-shaped and recessed at r and extended into a finger 0 wherewith another part of the mechanism engages, as will be explained later on. of the platform a lug s is secured thereto or made integral therewith, and a double-armed lever 25 is fulcrumed thereto to turn on pin 8'. On the end of the depending arm 6 of this lever a float z," is set, operating this lever by the inflow and outflow of the water. The other end t of lever 25 is extended to engage finger r of the drop-trigger. In addition to these two arms lever 25 is provided with a third arm 2?, depending beneath lever Z and hooked to engage this latter lever Z, as shown in Fig. 2. The hooked part of arm 5 extends under- On the other side neath the bent portion of lever Z in all positions of the mechanism.

The form of lever 1) is shown in Fig. 3 of the drawings. The bent end of its arm 3) extends underneath lever 0, and the bent end of its arm 19 extends across the depending arm t of lever t. Hooks 0 are shaped to allow turning of-the lever 19; but its downward motion is limited by the projecting base-plate of these hooks.

The operation of this mechanism is as fol lows: Starting with the position shown in Fig. 1, the tank is filled to the desired level. The lever 0 is in its lowermost position and in contact with arm p of lever 10. Both valves are closed, and lever c rests in recess r of the drop trigger q, thereby holding the latter in its uppermost position. 5.) Levers Z and t are disengaged from each other, the latter being also disengaged from finger r of the drop-trigger. Arm p of lever p restson arm 23 of lever 25. When handle f is pulled, lever 0 is lifted and trigger (1 drops, turning on its pivot until arrested by arm t Thereby recess 7" is moved out of alinement with lever 0, and when the pull on handle f is released the lever 0 drops on the cam-shaped head of the drop-trigger. (See Fig. 6.) Thus valve h is held open, and the water flows from tank A through outlet 7} into the bowl. The level of the water in the tank sinks, and both floats Z and Z descend with it. This descending motion of float 25' causes lever t to turn on its pivot in the direction of the arrow indicated in Fig. 1,whereby the hooked arm Z of this lever is brought in engagement with lever Z, hooks this lever, and thereby prevents further sinking of float Z and the resulting excessive opening of the inlet-valve. Float t continues to sink, and its arm [6 upon which the finger r of the drop-trigger has fallen whenlever cwas lifted, raises the drop-trigger again into such position where recess 1" is in alinement with lever c. This occurs when float t is in position shown in Fig. 2. Trigger (1 is then ready for engagement with lever 0. Then lever 0 drops, drawn by its own weight and by the pressure of water on valve h, into recess 7' of drop-trigger q, as shown in Fig. 5, thereby closing valve it upon the outlet-pipe Z. At this stage there is yet suflicient waterleft in the tank to prevent any air entering into the outlet-tube "Z, and the outflow of water occurs without any noise. The end of inflow-tube 7c is never exposed, and therefore no air can enter it. Float Z is held by the engagement of arm t with lever Z in the position shown in Fig. 2 until as float t rises with the inflowing water arm 6 is disengaged from lever Z, float Z then rising to the surface and closing the inlet-valve. Float t being disengaged from lever Zswings lever 25 in its position shown in Fig. 1, and the apparatus is ready for its next action.

If for some reason the inlet-valve should (Shown in Fig.

not operate and the flow of water should continue, the overflowing of the tank is prevented by the mechanism acting upon the lever 19 in the following manner: As hereinbefore stated, arm 0 of this lever is in position to be engaged by the depending arm t of lever t when this lever swings back to its position shown in Fig. 1, while lever 0 rests on the other arm 12' when sunk in recess 1" of the drop-trigger. Should the level of the water rise above its normal position, as shown in Fig. 1, float 2," being carried upwardly turns lever 23 farther in the direction opposite to the arrow indicated in Fig. 1 and lifts lever p, and thereby also lever cand valve it, connected with it. The outflow being thus opened, the water escapes from tank through pipei until the normal level is reached, when lever 0 again drops into its normal position, thus closing valve h, governing the outflow. Should the inflow of water gain, the float 6 will raise lever 0 until it is wholly disengaged from recess 1' of the drop-trigger Q. The drop-trigger then turns, thus holding the lever 0 in raised position, fully opening valve h, connected to it, and the water is discharged from the tank in the same manner as if handle f had been pulled to set the mechanism in action.
